Consider the following situation: Electrical engineers have a device that tests for battery life $($in minutes$)$ by placing a battery under a controlled electrical load and measuring how long it lasts. They are interested in comparing the performance of $4$ brands of batteries. They replicated the experiment $4$ times by randomly assigning a battery brand to be used in the electrical load device each time they measured battery life. In other words, they made $16$runs$$ and randomized the order in which the battery brands were used. The data they obtained was: Battery Brand Performance BrandA: $110,113,108,115$ BrandB: $118,116,112,117$ BrandC: $108,107,112,108$ BrandD: $117,112,115,119$

Brand A has been used for many years, while brands B$,$ C and D are new in the market. Also, only the brands C and D are solar powered.

Complete the following Table to provide information about some comparisons of interest.
